Things I learned lately 6 Apr


  • There's a lot of great new technology arriving to be used in passiv haus or net zero homes. For example, there's such a thing as a heat pump water heater. It extracts heat out of your home in summer (or all year long if you live in a hot climate) and puts the heat in the water, then pushes out cool dehumidified air into the house.
  • Back when vinyl was the usual medium to get music, recording engineers tried to put the quietest songs on the innermost tracks due to inner groove distortion.
  • There are two industries that kill more people than they employ. Coal and tobacco.
  • If you need to calculate 4% of 75, you could just swap the numbers for the same result. In other words, 75% of 4 is the same thing, which is 3.
  • The current Tesla model lineup spells S3XY.
